liver anatomy Flashcards
where is the liver anatomically located
right hypochondrium
Which ligament attaches the liver to the anterior abdominal wall?
falciform ligament
Which ligament attaches the liver to the anterior abdominal wall?
The falciform ligament attaches the anterior surface of the liver to the anterior abdominal wall, and forms a natural anatomical division between the left and right lobs of the liver.
Which vessels are responsible for the inflow of blood to the liver?
hepatic artery proper (25%) hepatic portal vein (75%). The hepatic veins are responsible for the drainage of the liver into the inferior vena cava.
The bare area of the liver is bounded by which hepatic ligament?
coronary ligament
Four lobes of liver
Caudate
